在研磨過程中，閥門制造的密封面是一個常用的整理方法，可以使龍安機械密封摩擦端面尺(chi)寸(cun)精度(du)(du)提高，閥門的(de)密封(feng)面，幾何粗糙度(du)(du)和表面粗糙度(du)(du)，但不(bu)能提高密封(feng)表面的(de)相互位置精度(du)(du)。

　　龍安機械密封面研磨包括五個方面的基本原理：研磨運動、研磨工藝、研磨速度、研磨壓力和研磨余量。研磨過程好一起研究密封面，隨著對龍安機械密封研(yan)究(jiu)(jiu)(jiu)的(de)(de)(de)(de)(de)復(fu)雜面(mian)(mian)(mian)，之間的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)和密封(feng)(feng)(feng)磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)研(yan)究(jiu)(jiu)(jiu)相(xiang)對運動(dong)(dong)時，密封(feng)(feng)(feng)圈(quan)表(biao)面(mian)(mian)(mian)，磨(mo)(mo)(mo)料磨(mo)(mo)(mo)具(ju)研(yan)究(jiu)(jiu)(jiu)部分和密封(feng)(feng)(feng)面(mian)(mian)(mian)之間的(de)(de)(de)(de)(de)滑動(dong)(dong)或滾(gun)動(dong)(dong)，切斷(duan)密封(feng)(feng)(feng)圈(quan)上(shang)薄薄的(de)(de)(de)(de)(de)一(yi)層金屬(shu)(shu)表(biao)面(mian)(mian)(mian)。密封(feng)(feng)(feng)凸峰部分的(de)(de)(de)(de)(de)圈(quan)，表(biao)面(mian)(mian)(mian)研(yan)磨(mo)(mo)(mo)，然后(hou)逐漸達到所要求(qiu)的(de)(de)(de)(de)(de)幾何形(xing)狀。不僅是(shi)金屬(shu)(shu)磨(mo)(mo)(mo)料的(de)(de)(de)(de)(de)研(yan)磨(mo)(mo)(mo)加(jia)(jia)工，以(yi)及(ji)化學作用。研(yan)磨(mo)(mo)(mo)油可使加(jia)(jia)工表(biao)面(mian)(mian)(mian)形(xing)成的(de)(de)(de)(de)(de)氧化膜，從而加(jia)(jia)快研(yan)磨(mo)(mo)(mo)過程。地面(mian)(mian)(mian)運動(dong)(dong)相(xiang)對運動(dong)(dong)的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)和密封(feng)(feng)(feng)圈(quan)密封(feng)(feng)(feng)圈(quan)的(de)(de)(de)(de)(de)研(yan)究(jiu)(jiu)(jiu)，對每個點的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)上(shang)的(de)(de)(de)(de)(de)道路和相(xiang)對滑動(dong)(dong)的(de)(de)(de)(de)(de)研(yan)究(jiu)(jiu)(jiu)應該是(shi)一(yi)樣的(de)(de)(de)(de)(de)。和相(xiang)對運動(dong)(dong)方(fang)向(xiang)改變(bian)。改變(bian)密封(feng)(feng)(feng)環內的(de)(de)(de)(de)(de)每個粒(li)子的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)上(shang)運動(dong)(dong)的(de)(de)(de)(de)(de)方(fang)向(xiang)不會(hui)重復(fu)他們的(de)(de)(de)(de)(de)軌(gui)跡，以(yi)避免磨(mo)(mo)(mo)損明顯增加(jia)(jia)了密封(feng)(feng)(feng)環的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)粗糙度。此外，運動(dong)(dong)方(fang)向(xiang)的(de)(de)(de)(de)(de)改變(bian)不能使磨(mo)(mo)(mo)粒(li)分布(bu)比(bi)較均勻，且均勻切斷(duan)金屬(shu)(shu)密封(feng)(feng)(feng)環的(de)(de)(de)(de)(de)表(biao)面(mian)(mian)(mian)。

　　龍安機械密封研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)是(shi)利用(yong)涂敷或者壓(ya)嵌(qian)游離磨(mo)(mo)(mo)(mo)粒(li)與(yu)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)劑的(de)混合(he)物(wu)(wu)，在一(yi)定剛性的(de)軟質(zhi)研(yan)(yan)(yan)(yan)(yan)具(ju)上，通過研(yan)(yan)(yan)(yan)(yan)具(ju)與(yu)工(gong)件(jian)(jian)(jian)向磨(mo)(mo)(mo)(mo)料施加一(yi)定壓(ya)力，磨(mo)(mo)(mo)(mo)料滾(gun)動(dong)與(yu)滑(hua)(hua)動(dong)，從被(bei)(bei)(bei)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)工(gong)件(jian)(jian)(jian)上去除極薄的(de)余(yu)量(liang)，以提高(gao)工(gong)件(jian)(jian)(jian)的(de)精(jing)度(du)(du)和降低(di)表面(mian)(mian)(mian)粗糙度(du)(du)值得(de)加工(gong)方法。按研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)時有(you)無研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)液可分為干研(yan)(yan)(yan)(yan)(yan)與(yu)濕研(yan)(yan)(yan)(yan)(yan)。研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)過程中(zhong)(zhong)，在研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)壓(ya)力下，眾多的(de)磨(mo)(mo)(mo)(mo)料微粒(li)進(jin)行(xing)微量(liang)切(qie)(qie)削。對工(gong)件(jian)(jian)(jian)表面(mian)(mian)(mian)進(jin)行(xing)擠壓(ya)、刻劃、滑(hua)(hua)擦(ca)；在研(yan)(yan)(yan)(yan)(yan)具(ju)運(yun)動(dong)中(zhong)(zhong)當研(yan)(yan)(yan)(yan)(yan)具(ju)壓(ya)嵌(qian)的(de)磨(mo)(mo)(mo)(mo)粒(li)脫落后及液中(zhong)(zhong)磨(mo)(mo)(mo)(mo)粒(li)相對工(gong)件(jian)(jian)(jian)發生滾(gun)動(dong)。研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)過程中(zhong)(zhong)，在研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)壓(ya)力的(de)作(zuo)用(yong)下，眾多磨(mo)(mo)(mo)(mo)粒(li)進(jin)行(xing)微量(liang)切(qie)(qie)削，同時被(bei)(bei)(bei)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表面(mian)(mian)(mian)發生微小(xiao)起(qi)伏的(de)塑(su)性變形，并且被(bei)(bei)(bei)加入的(de)諸如硬脂酸(suan)、油酸(suan)、脂肪(fang)酸(suan)等(deng)活性物(wu)(wu)質(zhi)與(yu)被(bei)(bei)(bei)研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表面(mian)(mian)(mian)起(qi)化學作(zuo)用(yong)。隨著研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)加工(gong)的(de)進(jin)行(xing)，磨(mo)(mo)(mo)(mo)具(ju)與(yu)工(gong)件(jian)(jian)(jian)表面(mian)(mian)(mian)間更(geng)趨貼(tie)近，其(qi)間充滿了微屑與(yu)破碎磨(mo)(mo)(mo)(mo)料的(de)碎渣，堵塞了研(yan)(yan)(yan)(yan)(yan)具(ju)表面(mian)(mian)(mian)，對工(gong)件(jian)(jian)(jian)表面(mian)(mian)(mian)起(qi)滑(hua)(hua)擦(ca)作(zuo)用(yong)。所以，研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)加工(gong)的(de)實質(zhi)是(shi)磨(mo)(mo)(mo)(mo)粒(li)的(de)微量(liang)切(qie)(qie)削、研(yan)(yan)(yan)(yan)(yan)磨(mo)(mo)(mo)(mo)表面(mian)(mian)(mian)微小(xiao)起(qi)伏的(de)塑(su)性流(liu)動(dong)、表面(mian)(mian)(mian)活性物(wu)(wu)質(zhi)的(de)化學作(zuo)用(yong)及研(yan)(yan)(yan)(yan)(yan)具(ju)堵塞物(wu)(wu)與(yu)工(gong)件(jian)(jian)(jian)表面(mian)(mian)(mian)滑(hua)(hua)擦(ca)作(zuo)用(yong)的(de)綜合(he)結果。

　　為了不讓泵水通過軸與密封間隙泄漏，由出口冷凝泵或在鹽水中的母管引至密封水。給水泵是一種具有一定溫度、高溫的水通過泵軸或泵體金屬容器用龍安機械密封將熱量傳給軸(zhou)承，使軸(zhou)承溫度升高(gao)。為了控制傳熱，所(suo)以密封的水也起(qi)到冷卻作用。

　　龍安機械密封直接冷卻就是冷卻液體直接和密封端面接觸達到冷卻的目的。沖洗實際上也是直接冷卻的一種方式，沖洗方式中通過管路連接換熱器將冷卻后的沖洗液引入密封腔進行直接冷卻。還有一種直接冷卻就是在龍安機械密封低(di)壓(ya)(ya)側(大氣)將清(qing)水(shui)(shui)、蒸汽等(deng)冷卻流體直接引(yin)入密(mi)(mi)封(feng)(feng)端(duan)泄(xie)露處的一種冷卻方(fang)式(shi)，也稱急冷，急冷不(bu)僅冷卻*，還能將密(mi)(mi)封(feng)(feng)端(duan)面(mian)周(zhou)圍的雜質及泄(xie)露液(ye)帶走，急冷液(ye)其(qi)壓(ya)(ya)力(li)比(bi)密(mi)(mi)封(feng)(feng)介質壓(ya)(ya)力(li)低(di)。急冷液(ye)應盡量采用(yong)軟水(shui)(shui)，以防(fang)止水(shui)(shui)垢產生破壞(huai)密(mi)(mi)封(feng)(feng)端(duan)面(mian)。當密(mi)(mi)封(feng)(feng)流體為易凝(ning)(ning)固、易結(jie)晶時，可用(yong)蒸汽、溶劑等(deng)防(fang)止流體凝(ning)(ning)結(jie)。
